McNary National Wildlife Refuge Professional Review and Guide
"The McNary National Wildlife Refuge is primarily a waterfowl preserve. The refuge encompasses many flooded fields, sloughs, and inlets along the Columbia River. It also sprawls across farmlands that provide winter forage for migratory birds. This area draws thousands of ducks, geese, and swans each year, usually beginning in November.
Look for tundra swans, redheads, cinnamon teal, green-winged teals, mergansers of all kinds, buffleheads, Canada geese, mallards, pintails, and the ever-present coots. Even when the migratory waterfowl are gone, the area is worth a visit. With desert on one side and the rich riparian area of the Columbia River on the other, an odd mix of birds and animals congregates at the refuge."
